22 Claims. (Cl. 199-59) This invention relates to new and useful improvements in typographical composing and casting machines.

As is well known, typographical c-omposing and casting machines are for the purpose of casting type with letters, words, figures, symbols and the like thereon for subsequent use in the printing of newspapers, books, and similar publications. Since different sizes of type are used in such publications, typographical composing and casting machines have in the past had means therewith for changing to a particular mold size for making the type size desired. Also, adjustable trimming knives have been provided for the purpose of making the sides of the type parallel so that adjacent blocks of type lie parallel to each other when set in a frame. Heretofore, the adjustment of the knives to correspond with the size of type in the particular mold being used was controlled by the `operator separately from the selection or changing of the mold to one for making a different size of type. With such separate operation, it often happens that the operator fails to select the proper knife setting when changing to a different mold with the result that the knives are either dmaged or misaligned, or the ejector lever is broken or damaged, or the operator loses productive time in order to readjust the machine for proper operation.

Furthermore, even under proper operating procedure with such old machines, the loss of operator time in changing the mold and shifting the knives to the corresponding position for the new mold is excessive since the operations must be successive if only one hand is used, or if both hands are used, it requires the operator to shift his body from the normal position in front of the keys of the machine. Additionally, in instances in which a type with overhang is employed, which are quite frequent in newspaper work particularly, the operator is required to use an eXtra overhang control so that the loss of time and chances for error are greatly multiplied.

lt is therefore an `object o this invention to provide a new and hnproved typographical composing and casting machine which is so constructed that upon changing from one mold to another mold, the type trimming knives are simultaneously set in the proper position for trimming the type to a size corresponding to the type size of the mold selected for use.

An important yobject of this invention is to provide a new and improved attachment for a typographical composing and casting machine which has means operated by a single control handle for simultaneously changing molds and setting the type trimming knives to correspond with the type size 4or" the changed mold, whereby damage or misalignment of the knives and other damage to the machine as well as lost time of the operator due to improper knife setting or failure to set the knives are eliminated.

Another object of this invention is to provide a new and improved attachment for typographical composing and casting machines which has means operated by a single control handle for selecting one of a plurality of molds for use in making the type, for setting the type trimarent O 2,839,182 Patented June 17, 1958 ming knives to a size corresponding with the particular mold selected, and for adjusting the knives to accommodate type having overh g, whereby manipulation for such operations by the o rat-or can be accomplished with only one hand and without requiring the operator to shift from his normal position in front of the keys of the machine.

Another object of this invention is to provide in a typographical composing and casting machine a new and improved means operable by rotation with the lingers of one hand for rapidly opening the type trimming knives of said machine to permit the type with overhang to pass through the knives without obstruction.

The construction designed to carry out the invention will be hereinafter described, together with other features thereof.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings forming a part thereof, wherein an example of the invention is shown, and wherein:

Figure l0 illustrates a modification of the structure illustrated in Figure 9.

In the drawings, the letter A designates a mold disk which lis a part of a typographical composing and casting machine such as manufactured under the trade names, lntertype and Linotype As is well known, such typographical composing and casting machines have means for casting letters, gures, symbols, or the like in a section of type or type block for subsequent use in the printing of newspapers, magazines, and similar publications. ln such machines, the mold disk A carries a plurality of type molds l@ which are removably mounted on the circular body l1 of the mold disk A, and each of the molds lll is Aordinarily of a diterent internal size for making different sizes of type. In the ordinary machines of this type, the body 11 of the mold disk A is mounted on a central shaft l2 which is horizontally disposed so that the mold disk A lies in a vertical plane for rotation therein. The mold disk body il has gear teeth 14 around its periphery which mesh with the gear teeth 15a on gear 15 which is connected to the conventional drive mechanism of the machine (not shown). Thus, with the `drive gear l5 engaged with the power source (not shown) of the typographical machine, the rotation of such gear 15 is transmitted to the mold disk A to eiect a rotation of same. When the gear 15 is disconnected from the power source of the machine, the mold disk A can be rotated manually by the rotation of gear 16 which drives the -mold disk A by the engagement of an idler gear 17 with the gear teeth 14.

`linkage K (Figure 9). p Y knife `setting mechanism S through a set of gears G Briefly, the attachment device ot this invention includes a single control handle 2i) which is adapted -to be- COnwhereby Vupon a rotation of the mold diskl A with the handle 20, the knife setting mechanism S is also operated ina synchronized relationship so as to adjust thel type trimming knives and 26 to a proper position corresponding to the particular size of the mold being used.

Also, as will be fully explained hereinafter, the knives 25 and 26 can be fully opened by a manipuiation of the handle 29 in instances in which the type has overhang formed therewith. v

Considering the attachment or improved device of this invention in detail, the control handle 2i) is connected to an operating shaft 2S so that the turning orrotation of ythe handle 2t) .effects a turning or rotation of the shaft 28.V The shaft 28 has a hollow bore or recess 28a (Figure 2) in which a rod 30 is positioned for movement relative to the shaft 28. The rod 30 is urged inwardly by a spring 31.which is disposed in the bore 28a and connects with the inner end 39a Vof the rod 34B and a pin 32 in the bore 2801.V A stop lug 33 extends-laterally from the rod 30 and serves to limit the extent of inward movement of the rod 30 withrespect to the shaft 28 and alsothe rotational movement of the shaft 2S with respect to the rod 30. The lug 33 is adapted to t intora notch 28b lat the .end of the shaft 28. Also, upon a relative turning of-the shaft 28 with respect to the rod 30 and lug 33, the lug 33 moves along the edge 28e of the shaft 28 kand is adapted to engage in a notch 23d which is diametrically disposed with respect to the notch 2Sb. Thus, the lug 33 is adapted to move relative to the shaft 28 throughout onehalf of a revolution of the shaft 2S. However, the lug 33 Vis normally retained in the notch 28h and is only moved to the oppositely disposed notch 28a toadjust the knife setting mechanism S to accommodate type having overhang, as will be more fully explained. VThe rod 30 has anenlarged outer section 30E: with the connecting member 22 mounted therewith. The connecting member 22 is formed with ya groove 22a into which a connecting projection 35 is adapted to extend for establishing a releasable connection between they handle 20 and the gear 16. Such projection 35 is carried by a connecting head 36 which is formed on stub shaft 38. Such shaft 38 extends through a cylindrical bore or bushing 37a in a iixed support 37 of the machine and then also extends through the gear 16 and has an end thereof in contact with actuating lever 4t). A key 33u is carried by shaft 38 and is adapted to alternately move into key way 37b and keyway 16a. Normally, when the automatic operation of the machine is being carried out so as to move the mold disk A in its predetermined sequence of operations, the gear 16 rotates freelyon the shdt 38, and the ykey 38a is in the keyway 37b, but upon a movement of the shaft 38 to the right (Figure 1), the gearv 16 is moved into driving engagement with the shaft38. Such arrangement is conventional and is well known but for illustration purposes, key 38a is illustrated on the exterior of the shaft 38 to indicate that when theshaft 38 is moved to the right, the key 38a extends into keyway 16a so that the gear 16 and the shaft 38. then are connected for rotation together.

During the connection of the shaft 38 with the gear 16, the lever is actuated by the end of the shaft 38 and is moved to the right (Figure l)` to release theimold disk Afrom its automatic sequence of operations. Such release is effected by the connection of the lever .40 tothe gear 15 through the pivot rod 41 supported on .the base of the machine by. bushings 42, with suchirodl being 'connected to an operating lever 44. The lever 44 hasa -v--yokev which transmits movement of the `lever '44 to the gear 15 to move it longitudinally so as to disconnect the gear 15 from the driving power source of the machine, whereby the gear 15 no longer drives the mold disk A. With such arrangement, it will be evident that upon a movement of the lever 40 rearwardly (Figure 9) or to the right (Figure l), the shaft 41 is turned in its bushings 42 so that a corresponding rearward movement of the lever 44 is obtained to thereby shift the gearS rearwardly. v

However, when theY handle2t) is not manually pushed rearwardly, the lever 44 is urged lforwardly (Figure 9) by a spring which is anchored to the lever'4t) and to a xed portion 51 of. the machine. The forward urging of the spring 5i) on the lever 40 is also transmitted to the stub shaft 38 so as to normally maintain the shaft 38 in the disengaged position with respect to thegear 16. Additionally, the -enlarged portion 30a of the rod 31) has a key 55 mounted therewithk which is normally urged outwardly or to the left (Figures 1 and 2) so that when the key 55v is longitudinally aligned with the key slot 56, the key 55 is urged into such slot 56. When the key 55 is in the slot 56, the groove 22a in the connecting member 22 is aligned with the projection 35 of the connecting head 36. When the handle 2t) is manually moved inwardly or rearwardly to connect the members 22 and 36 togethen'the key 55 is moved out of the slot 56 to a position shown in Figure 1 so that the handle 20, shaft 28 and the rod 39 can be rotated or turned with the enlarged portion 39a moving relative to and within the cylindrical bearing member 57 in which the keyway or slot 56 is formed.

ln order to drive the set of gears G by the manual manipulation of the handle 20, the shaft 28 has a longitudinal keyway 28e (Figures 1 and 2) formed in its external surface for receiving a key 6i) which is connected to a gear 61 mounted on the shaft 28. Gears 62 and 63 are positioned above the gear 61 for transmitting the f rotation of the handle 20 to a pinion gear 64 (Figure 3) which is connected to the stub shaft 65 on which the gear 63 .is mounted. The gear 62 is mounted on a stub shaft 66 and allof the gears 61, 62 and 63 are positioned between fixed guide and support brackets 67 and 68 which have connection through bracket arm 69 to bearing member 57. y y

The side bracket 68 hasa lateral extension 70 to which is attached a gear support plate 71 by screws 72 or any other suitable securing means. The support member 71 is also connected to a ring 75 by screws 76 or any other suitable securing means. As shown in the drawings, the screws 76 extend through extensions 71a on the support member 71 (Figure 1).` In this manner, the ring 75 Vis thus supported and fixed against movement. The support member 71 has an opening 71h therethrough for receiving a cylindrical bushing 77 which is attached to the ring by the welds 78 or other suitable connecting means between the lateral bushing extension 77a and the ring 75 (Figure 3). The interior of the bushing 77 is threaded to receive the bolt 79 for connecting the member 71 to the collar 87 and for the mounting-of an ndicator or pointer 80 on the side of the support member 71.

A bevel gear 81 having the bevel gear teeth .81a extending n an annular ring thereon is positioned on the bushing 77 for rotation relative thereto upon a rotation of the pinion gear 64. The bevel gear 81 has a plurality of cam buttons 82 mounted therewithand the number of cam buttons 82 corresponds with the number of molds 1 0 in the mold disk A. Also, the spacing of the cam buttons 82 corresponds with the spacing of the moldsl on the disk A. In other words, there is a cam button 82 for each mold 10 so that in thestructure illustrated, there are six molds 10 which are an equal arcuate distance from .each other and there are six cam buttons 82 escasa which lie in a circle and are equally spaced from each other, the purpose of which will hereinafter appear. Although the cam buttons 82 may be positioned on the bevel gear 81 in numerous ways, as illustrated in the drawings (Figure 3) the buttons 82 are threaded into correspondingly threaded openings in the gear 81 and an opening 71e is provided for the insertion of a screwdriver for effecting an adjustment of the height of each cam button 82 from the surface of the bevel gear Si. The cam buttons 82 are adapted to engage cam surface 83a of a cam member 83 which is formed integrally or otherwise connected to a longitudinally movable knife setting sleeve 84. The cam surface 83a has a central portion 83b which provides for maximum movement of the sleeve 84 by reason of the engagement of one cam button 82 at a time with the cam surface 83a. The cam surface 33a also lies in an arc which lies in the circular path of the cam buttons S2 so that as the gear 81 rotates relative to the cam member 83 and the sleeve 84, the cam buttons 82 successively engage the cam surface 83a. The sleeve 84 is provided with arcuate openings 84a (Figures 3 and 4) through which the cam buttons pass so as not to contact the sleeve 84.

The sleeve 84 is guided in its movement relative to the bevel gear 81 by a guide cylinder 85 which is welded at 86 or is otherwise suitably secured to the ring '75. The ring 85 has external threads 85a which engage with internal threads 87a on collar 87 which is secured to the frame of the machine by suitable means (not shown). Of course, any other means for connecting the cylinder 85 to the collar 87 could be utilized, but the threaded arrangement permits disassembly and attachment of the improved device of this invention to the standard collar 87 which is presently on typographical composing and casting machines.

A knife block S8 which carries the movable knife blade 25 is mounted for movement with the knife setter sleeve 84 by means of positioning pins 89 which extend into openings 84b in the sleeve 84. The pins 89 are threaded or otherwise connected to the block 88 and nuts 9|) are provided to initially adjust the block 88 so that the knife 25 is parallel with the Xed knife 26 which is mounted on the frame 91. A coil spring 92 urges the knife block S8 toward the sleeve 84 at all times so as to maintain the nut 90 resting in contact with the annular surface 84e of the sleeve 84 at all times. The spring 92 has one Vend thereof connected to a hook 93 which extends into the bore 88a of the knife block 88 and at the other end, the spring 92 is connected to a bracket 94 which is secured to the collar 87 or some other suitable portion of the frame which is fixed against movement. Thus, as the cam buttons 82 of different heights move into contact with the maximum displacement portion 83h of the cam surface 83a, the sleeve 84 and the knife block 88 with the movable kmfe 25 are correspondingly moved diiferent amounts so that the spacing between the knives 25 and 26 varies in accordance with the height of the particular cam button 82 which is in contact with the cam surface 83. The knife 25 always remains parallel to the knife 26, because there is substantially no tolerance or space between the external surface of the sleeve 84 and the guide bushing 85 so that during the relative movement of the sleeve 84 with respect to the cylinder 85, no substantial tilting of the sleeve 84 occurs and therefore no appreciable tilting of knife 25 out of parallelism occurs. Thus, since the movable knife 25 is moved parallel to the fixed knife 26 so as t0 be spaced different distances from such ixed knife 26, in accordance with the partisular cam button 82 which is in engagement with the cam surface 83, the particular spacing of the knives 25 and 26 which is desired is controlled by regulating the heights of the cam buttons 82 in accordance with the distance required between the knives 25 and 26 for the various mold sizes of the molds 10 in the mold disk A.

For example, when a particular mold disk having a predetermined width for making a particular size of type is in use, the knives 25 and 26 must be spaced from each other a distance to correspond with the width of that mold l0. Therefore, there must be a cam button 82 which corresponds in height with-the knife setting required for each mold so that when a particular mold is being used, the cam button 82 which corresponds with such mold is in Contact with the central maximum movement portion 8311 of the cam member 83. Thus, assuming that each mold 10 in the mold disk A is for a different size type and therefore is of a dierent width, the cam buttons 82 would all be of different heights and would be so positioned that they would move the movable knife 25 to the correct spacing for the mold being used. To illustrate, if the mold 10 which is shown opposite the knives 23 and 26 in Figure 5 is the mold being used, and the cam button 82 (shown in Figures 3 and 4) is the one in engagement with the cam surface 83 for properly spacing the knives 25 and 26, then if it is desired to use the mold 10 which is adjacent and clockwise (Figure 5) from the mold 10 illustrated in front of the knives 25 and 26, the cam button 82 which is clockwise (Figure 4) from the cam button 82 under the cam surface 83 would have to be positioned under the cam surface 83 in order to obtain the correct knife setting. For indicating which size of mold disk is in the proper position for use, the periphery Sib (Figures l and 4) of the bevel gear 81 has numbers or symbols adjacent each cam button 82 which corresponds with the molds and the pointer or indicator S0 is disposed adjacent the peripheral surface Sib so that the operator can readily determine which size of mold is in position for use.

In considering the operation or use of the device of this invention in connection with the typographical com posing and casting machine, let it rst be assumed that the mold disk A is being operated by the automatic mechanism which rotates the mold disk through the gear 15. Such automatic operation is known and the basic automatic sequence starts with the particular mold it? being used in a position in front of the type-trimming knives 25 and 26 (Figure 5). For convenience, such mold is designated X in Figure 5. When the automatic operation is started, the mold disk A is rotated counterclockwise to position the mold X ninety degrees from its original position and at the top position. In that top position, the type metal is poured into the mold and the letters or other symbols are formed on the type in the mold. Then, the mold disk A is again rotated counterclockwise to move the mold X back to its starting position opposite the knives 25 and 26. In that position, an ejection mechanism (not shown) of conventional construction operates to move the slug or block of type from the mold X through the knives 25 and 26 so that the knives 25 and 26 trim the sides of the block of type parallel to each other. It will thus be evident that in the automatic sequence of operations, for a particular sequence beginning with the formation of the type and ending with the ejection of the type to the knives, oniy one of the molds it@ is used. When it is desired to use a dierent size of mold it), then the automatic mechanism must be disengaged and the manual device of this invention is utilized for such changing operation.

Assume therefore that it is now desired to use the mold next below the mold X, which for convenience is designated with a Y. To move the mold Y into the starting position occupied by the mold X in Figure 5, the handle Ztl is moved inwardly or rearwardly to move the shaft Z5 relative to the gear 61 and the rod Si) and its enlargement 3&1 relative to the bushing 57. During such movement, the key 55 moves out of the slot 56, but prior to the time that it completely leaves the slot 56, the connecting member 22 is engaged with the connecting head 36 by the positioning of the projection 35 in the groove 22a. Upon the completion of the connection between the member 22 and the head 36, the stub shaft 38 is moved inwardly or Vrearwardly to pivot the lever 40 against the action of the springtStl so as to disconnect the automatic drive to the mold disk A through the gear 15. Also, the inward movement of the 'stub shaft 38 engages the splines 38a or other suitable engaging means `with the gear 16 so that rotation of the shaft 38 is thereafter imparted to the gear 16. Thus, when the shaft 38 and the gear V16 are fully engaged for rotation together and the gear vl is disengaged from automatic operation of the molddisk A, the key 55 has move-:l rearwardly a suiiicient distance to be completely free of the keyway or slot 56 so that thereafter the handle 2) can be rotated. Whenthe key 55 is thus displaced from the slot 56, the rotation of the handle 2Q ettects a rotationV of the shaft 28, rod 30, and rod enlargement 3fm, con- Vnecting members 22 and. 36, shaft 33, and gear 16. .Thence, the gear16 is in driving engagement with the mold disk A through the idler gear 17, the rotation of .thel gear 16 effects a rotation of the mold disk A. The

gear ratio between the gears .16, 17 and i4 is such that upon making one complete revolution of the shaft 28, the mold Y is moved to the position occupied by mold X in Figure 5; that is, for each revolution of the shaft 2S, the mold disk A is moved one-sixth of a revolution.

Also, the rotation of the shaft 2S imparts a rotation to the gear 6l due to the key 69 mounted in the keywa'y 28e of the shaft 28. The rotationV of the gear 61 is transmitted to the gears 62 and 63 and to the pinion gear 64 which meshes with the bevelV gear 8l, for rotating same. Assuming that the mold disc X was initially in position in front of the knives Z5 and 26 prior to the manipulation of the handle 20, then the cam button 82 which is identified by the letter X' (Figures 3 and 4) was in contact with the central portion 83h of the cam' the bevel gear 81 one-sixth of a revolution for each revoy. L

lution of the handle 20 can be obtained by employing a twelve-tooth pinion gear 6d and a seventy-two tooth bevel gear 81.

Since the cam button Y is of a height which corresponds with the thickness or width or the mold Y, the

knives and 26 are adjusted to correspond with the thickness or width of the mold Y. Thus, if the width or thickness of the type formed in thesmold Y is less than the thickness of the type formed in the mold X, then the cam button Y will extend above the face of the bevel gear Si a greater distance than the cam button X so that when the cam button Y' is moved into contact with the maximum central cam portion 831:, the knife 25 will be moved toward the fixed knife blade 26 so that the space between the knives 25 and 26 will be less than when the `cam button X was in contact with the maximum cam portion 33h.

When the cam button Y is in position below the maximum portion S31; ofthe cam member S3, the mold Y is also in position infront of the knives 25 and 26 for the start of the automatic sequence of operation employing the mold Y forthat particular sequence. Also, at that time the key 55 is aligned with the slot 56 and unless lan inward force is maintained by the operator on the handle 20, thespring pressure of the'spring 5 acts through-the lever 4@ to shift the shaft 3S and the enlargement a to move the key 55 into the slot Se. As the handle 2i) is thus retracted to completely position the key 5S within the slot 56, the spring pressure of the spring 5tlcompletely. disengages the splines 33a on the shaft 38 from the, gear 16 Vso that the gear,-16 is then freeto move relative tothe shaft 38 andthe lever 40 in moving outwardly (to the left in Figure 1) effects a re-cngagement of the gear 15 with the mold disk A for the automatic operation. The connecting member 22 is then ultimately disengaged from the connecting head 36 in the usual case, although it is possible to Varrange the ,device so lthat the connecting members 22 yand 36 never completely are released from. each other due to the fact that the gear 15 does not have-a driving connection with the shaft 33 when the key 38a is released from the Vkeyway 16a. In any event, the handlekitl is locked against rotation by means of the key` inthe slot 56. Thus, the handle 20 is again in the starting position and is inactive. lt should also be noted that if another of the molds such as the one designated Zin Figure 5 had-been d sired instead of the mold Y, then to position the mold Z in the starting position occupied by the mold 5X in Figure 5, it would have required two revolutions of the handle 20. Also, two revolutions of the handle 20 would positionrthe cam button S2 which is designated by the letter Z underneath the centralportion 83h of the camy surface 83 so as to space the knives 25 and 26 from each other a distance` correspondingrto thel height of the button Z which ispredetermined in accordance with the width of the mold Z. Similarly, to have positioned the mold F in the position occupied-bythe mold Xin Figure 5 wouldrhave required three revolutionsr of theVV handle 2t). 1t should also be noted thatalthough the above-described manual manipulation of the handle, 20

.Y was in a rdirection to move Vthe mold disk Ain a counterclockwise direction (Figure 5), the handle 20 can Valso be movedin a clockwise direction so that if moldsvD or E or F are desired, the rotation of the handle 20 may he clockwise (Figure 5) one revolution, -two revolutions or three, revolutions, respectively. .'Ihus, not more than three revolutions ofthe handle 20 is required to move the disk A to any desired mold 10. Also,.on the positioning ofany of the molds X, Y, Z, D, E, or F in position for use during a particular sequence of automatic operations, one of the corresponding cam buttons X', Y', Z', DQ E( or F', respectively, is positionedfin contact with the central portion 831; of the cam 83.

The device of this invention can also be used Vfor ,adjusting the knives 25l andv26 to accommodate type in any of themolds which has overhang formed therewith during a -particular operation. Thus, with a particular mold i@ in the starting position in front ofthe knives 25 and 26 and with the handle 20 in its normal inactive position with the key 55 in the slot 56, when it is desired to adjust the knivesZS and 26 for accommodatingoverhang, such can be readily accomplished by pulling ythe handle '20 outwardly (or to the left in Figures 1 3). Upon the outward movement of the handle 20, the shaft 2:3 is moved outwardly relative to the rod 30, since the rod 38* is limited against outwardl movement by the contact of the outer end 55a of the key 55 with theinner endV 56a of Vthe slot 56, or any other .suitable stop means. The relative movement between the shaft 128 andthe rod 3th also effectsr a movement of the lug 33 out of the notch 281; (Figure l) by the movement of the shaft 2t?. away from the lug 33. Then, upon a rotation of the handle v2G in a counterclockwise direction, as .iew'ed in Figure 9, the shaft 23 is rotatedV relative to the rod 3i) and the lug 33- slides along lthe end surface fsc during such relative rotational movement. The rotation of the handle 20 is, however, stopped when the handle has been moved one half of a revolution since the lug 33 is then adjacent or opposite the other 'recess and therefore further rotation of the shaft 28 relative to the rod 3a is prevented. It will be evident that as the shaft 23 is rotated, the connection ybetween 'the shaft 2?, and the gear 61 effects a rotation-of the gear ,6i whichin turnrotates gears62 and 63fto drive Vthe pinion gear 64, 13nd; the; bevel :gear 81, .whereby thefbevel assenso j `gear 81 is moved one twelfth of a revolution or one half of the distance normally required to move a cam button from the position below the central portion 831: and to move another cam button 82 into that position. Under such circumstances, none of the cam buttons 82 is in contact with the cam surface 83 and therefore the spring 92 pulls the knife block 8S and the sleeve S4 into a completely retracted position with the lower sur- 'face 84d of the sleeve 54- stopped in contact with the upper surface 77h of the bushing 77 (Figure 3). Thus, the knife 25 is moved to a fully opened position and is the maximum distance from the lxed knife 26.

If it is desired to open the knives a distance less than maximum for smaller sizes of type with overhang, the handle 20 is simply rotated less than a complete onehalf revolution in which case, one cam button 82 will still be in contact with the cam surface 83a but it will not be at the maximum central portion @3b. Thus, it will be appreciated that although the knives are ordinalily spaced apart a maximum amount for overhang, an infinite number of overhang adjustments are possible.

After the mold is used for making type with overhang, then the knives 25 and 26 can be returned to their normal operation by reversing the rotation of the handle 20 in a clockwise direction (Figure 9) so as to move the lug 33 back into the original notch 28h. Thereafter,

the mold disk A can be rotated to change the particular mold being used and the corresponding change in the knives will also be effected in the same manner as explained previously, and at any time that it is desired to adjust the knives 25 and 26 for overhang, such adjustment is made as explained irrespective of the particular mold in use at the time the overhang is formed. It should be pointed out that the adjustment for overhang is made with the same handle 2t) as is used for changing the molds and the knife settings.

In some typographical composing and casting machines now being built, such as those built under the name Linotype, the gear 15 is disengaged upon a forward motion instead of a rearward motion as previously explained in connection with Figure 9. In such case, the modification illustrated in Figure is employed so that the lever 140 connects with shaft 41 instead of the lever 40 of Figure 9. Also, a spring 159 which is connected to the frame at 151 pulls the lever 146 rearwardly and therefore such spring 150 is used in place of the spring 59 of Figure 9 so as to obtain a reverse normal movement of the lever 140 as compared with the lever 40 of Figure 9. The lever 14o acts against an additional pivot lever 9d which is mounted on a pivot pin 91 so that the urging of the spring 1d@ exerts a pivoting force on the lever 9d to pivot the upper end thereof forwardly. Therefore, the shaft 3S is urged forwardly in the same manner that shaft 38 is urged forwardly in the form of the invention of Figure 9, but, upon a rearward movement of the shaft 38, the lever 90 is pivoted and moves the lever 149 forwardly instead of moving rearwardly as in the case of the lever 4t). Thus, the gear connected through the rod 41 from the lever 140 would be moved forwardly which would disengage same in the Linotype machine.

It is thus believed evident that the modification of Figure l() operates in conjunction with shaft 38 in the same manner as the form shown in Figure 9 except for the reverse movement of the lever 140 and the gear 15 as compared to the lever 4G and gear 15 of Figure 9.

In Figures 6, 7 and 8, a modified portion of the knife setter mechanism is illustrated wherein the cam member 83 and the cam buttons 82 of Figures l-4 are modified. Thus, the cam surface la is identical with the cam surface 83a and has a similar maximum projection or central portion 18317 which corresponds with the central portion 83h of Figure 4. However, in connection with the cam member 183, alignment studs 92 and 93 are mounted therewith adjacent the ends of the cam surface lfa and on opposite sides thereof. Such studs 92 and 93 preferably extend from the cam member 133 the same distance.

In the modified construction, the cam buttons 182 are threaded through suitable openings in the bevel gear 181 (Figure 7). Each cam button 182 also extends through an opening 94a in -a central portion 94 of bracket B which has angularly extending arms 95 projecting therefrom to end sections 96. The upper portion 94E: (Figure 7) of the opening 94a is enlarged for receiving the head T.Zo of cam button 182 so that as the cam button 182 is adjusted with respect to the gear 181 by rotating same, the bracket B is moved inwardly therewith. For maintaining the bracket B in cont-act with the head 182er and also for frictionally locking the threads of the cam buttons 1.32 in the gear 181, a coil spring 97 is disposed between the gear 181 and the central portion 94 of the bracket B for urging the bracket B and the gear 181 away from each other. Fach of the end sections 96 is provided with an internaliy threaded bore 96a which receives the alignment pins 98 99 which extend slidably through the gear 131 so that the ends thereof can contact the ends of the alignment studs 92 and 93, respectively. By threading the pins 98 and 99 inwardly or outwardly within the end sections 96 with which they are connected, the `alignment thereof can be adjusted so that when the ends of the pins 9S and 99 are in contact with the ends of the studs 92 and 93, respectively, the slidable sleeve 134 is likewise adjusted to position the movable knife 95 parallel to the fixed knife 26. It can therefore be readily appreciated that a parallel adjustment is provided at each knife position and, also, due to the contact of the cam button 132 with the maximum central portion 183]; of the cam surface 153m and the simultaneous contact of the alignment pins 93 and 99 with the alignment studs 92 and 93, respectively, there is a three-point support for the slidable sleeve ld to assure the stability of the sleeve during its longitudinal movement and to thereby prevent any tendency of the sleeve 184 to tilt the knife 25 out of parallel adjustment with respect to the knife 26 even though there may be some space between the exterior of the sleeve 184 and the bushing 85 which might otherwise permit tilting. As in the form of the invention shown in Figures 1 4, this form of the invention in Figures 6-8 has a cam button 182 for each mold 10 on the mold disk A, and, of course, each cam button 132 has associated therewith a bracket B with the pins 9S and 99 (Figure 6).

The center of the bevel gear 1S1 is so disposed with respect to the center of the sleeve 184 that the cam buttons 182 all travel `along the arc defined by the cam surface 183g (Figure 6). Also the pins 9S and 99 are disposed so that the ends thereof contact the ends of the pins 92 and 93 when the cam button 182 associated therewith is in contact with the maximum central portion 183i; of the cam 183. Further, the pins 98 with each bracket B all rnove in the same circular path and likewise the pins 99 all move in the same circular path. The sleeve 184 has slots or openings 1%412 on eac-h side thereof which are of sufficient width to allow the pins 98 and 99 and the cam buttons 132 to pass therethrough without contacting the sleeve 134 (Figure 6).

In some cases, the particular molds 10 in the mold disk A are changed to obtain different sizes than are provided by the six molds in 'the disk, and in such case, the cam buttons 182 can each be individually adjusted, along with the pins 9S and 99 to change the knife settings to correspond with the new molds utilized. If desired, an indicator 1d@ (Figures 6 and 7) can be mounted on one of the arms 95 of each bracket B for pointing or indicating the position of the cam button 182 which can be adjusted according to indicator marks M (Figure 6) placed on the top surface of the cam button head 182e. Therefore, accurate and controlled adjustment of the knives can be readily obtained to compensa-te for any s particularsize of mold being used in themold disk A. The operation of the Ymodiiication of Figures, 6-8 is believed evident from the foregoing description and it l will be evident that the cam buttons 132 function in the studs v92 and 93. Except for the above main differences in operation,fthe ,modication of Figures 6 8 `functions in the same manner as that form shown in Figures 1-4.

It should be pointed out that although the invention has been disclosed in connection with a mold disk havv.ing six molds therewith, the invention is equally applicable to machines in which a different number of molds are employed. t

From the foregoing, it is believed evident that an attachment or improvement for a typographical composing and casting machine has been provided which not only provides for simultaneous adjustment of the type trimming knives with the selection of a particular mold, but

also provides for the adjustment of the knives to accommodate overhang with a single control handle, whereby the operator of the machine is required to use l only one hand, ordinarily his left hand, for performing all three operations.

The foregoing disclosure and description of the invention is illustrative and explanatory thereof and various kchanges in the size, shape and materials, as well as in the details of the illustrated construction, may be made within theJ scope of the appended claims withoutvdeparting from the spirit of the invention.
